`luly 12, 1932. H. J. GAlsMAN SAFETY RAZOR Filed April 17. 1931 NVENTOR fry J wllffmfz ATTORNEY Patented July 12, 1932 UNITED STATES PATENT OFFICE HENRY J. GAISM'AN, OF NEW YORK, N. Y., ASSIGNOR T0 GILLETTE SAFETY RAZOR COMPANY, F BOSTON, MASSACHUSETTS, A CORPORATION 0F DELAWARE SAFETY RAZOR Application led April 17,

The object of my invention is to provide a safety razor in which blade clamping members are movably retained together and in which said members may be moved to dier- D ent positions relative to a handle attached thereto, the means that retain the blade clamped for shavingalso serving to retain the clamping means and the blade in shaving position with relation to the handle. l0 In carrying out my invention Iy provide blade clamping members including a guard and a cap or blade backing, pivotally connected together, a handle attached to the .guard member, and means operative within "c the handle to engage the cap or backing member to retain the latter clamped against the blade, whereby when said means are released from the cap the latter may be swung away from the blade for removal and replacement.

My invention also comprises novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims.

In the accompanying drawing- Fig. 1 is a side elevation ofa portion of a razor embodying my invention, with the parts in shaving position;

` Fig. 2 is a cross section on line 2, 2 in Figure 3; Y c

Fig. 3 is a cross section on line 3, 3 in Figure 1; v

Fig. 4 is a view similar to Figure 3 showing the cap or backing member in released position; A

Fig. 5 is a plan view showing the parts spread for removal or applying a blade, and

Fig. 6 is a side view showing the parts in position for storage.

Similar numerals indicate corresponding parts in the several views.

The numeral 1 indicates a guard member, which may be, generally, of any desired construction, and at 2 is a cap or blade backing member, a blade 3 being adapted to be clamped between said members in shaving position. Y The members 1 and 2 are pivotal- 1y connected at adjacent ends as by means of a pivot 4 carried by one of said members, such as the guard member, and operative in a slot 5 in the other member, such asthe cap 2,

whereby said members may have relative lateral movement for clamping the blade between them. rI'he cap or backing member 2 is shown provided with projecting means at 6 adapted to enter a suitable aperture 7 in the blade to position the latter with relation to the guard and the cap. The guard member 1 is shown provided with a longitudinal groove 8 to receive the projecting means 6. At 9 is a handle, shown pivotally connected with the guard member 1, for which purpose said member is shown provided with spaced ears,-b etween which the adjacent end of the handle is fitted and pivotally attached there-v to by means of pivots 11, shown in the form of screws having circular bearing ortions 12 journaled in bearing holes 13 in t e ears 10, the screws being attached to the handle, wherebythe handle and the guard are piv- 'otally connected so that the guard may be set in shaving position with respect to the handle, as shown in Figure 3, or may be turned to a position substantially parallel to the handle, as for storage, as shown in Figure 6.

For clamping the blade between the members 1 and 2 I provided a rod 14 that is slid-v able in a longitudinal bore 15 in the handle 9 and between the screws or pivotsI 11, and through an opening 17a in the guard member 1. The rod 14, at its outer end, is shown provided with screw threads at 16 adapted to mesh with the threaded bore 17 in the cap or clamping member l2, as illustrated in Figures 2 and 3. When the rod 14 is released from member 2 the latter may be swung on its pivot 4 away from Vthe guard member to permit removal and replacement of a blade. By preference I provided' a spring' 18 cooperative with the handle 9 and with rod 14 normally tending to move therod in a direction away from the cap member 2. Rod 14 is shown provided with a stop or shoulder 19 slidable in an enlarged -portion 15a on the bore1 15, thespring 18 bearing against said stop and against an abutting stop portion 9a 95 of the handle. The normal expansion ofthe spring 18 tends to move the rod 14 outwardly to withdraw the rod from the cap member, as illustrated in Fig. 4. The rod 14 is also shown provided with a stop shoul- 10 Ader 20, (Fig. 2), which is adapted to engage a plug 21 shown secured by threads at the outer end of the bore of handle 9. A iingerpiece 22 secured at the outer end of rod 14 permits manipulation of said rod, and is adapted to abut against the end of the handle rvhen the parts are in shaving position, as in To apply a blade the members 1 and 2 are swung apart, as illustrated in Fig. 5, a blade 3 may be placed upon the cap or backing member 2 and positioned thereon, the projecting means 6 entering the aperture 7 of the blade, and then the members 1 and 2 are swung together with the blade therebetween, the rod 14 being normally retracted from the backing member, as in Fig. 4. The rod 14 will next be pushed inwardly, against the tension of the spring, to engage the threads 16 in the threaded aperture 17 of the cap member, and by rotating the rod the cap member will be drawn toward the guard member to clamp the blade between said members, the pivot 4 and slot 5 permitting lateral move.

`ment of said members for the clamping purpose, as in Fig. 3. The spring 18 will be compressed between the stops y9a and 19 and will serve to resiliently assist the clamping of the guard and cap members against the blade. Although the handle is pivoted to the guard against the blade, and meanspivotally-connecting said members at ad]acent ends to permit said members to have movement toward one another while clamping a blade therebetween. I

3. A safety razor comprising a guard mem'- ber and a blade backing member, the guard member having spaced ears, a handle having a portion between said ears and pivotally atv tached thereto, said handle having a longitudinal bore extending between said ears, andl a rod slidable in said bore and through an Aopening in the guard member, said rod and member, the rod 14, being slidably guidedin the handle, will engage the cap member, as in Fig. 3, and the blade holder, comprising the members 1 and 2, will be retained by the rod substantially at a right angle with respect to the handle in shaving position.y When the "rod 14 is released from'the cap member, (Fig.

4), the latter may be swung away from the guard member around thepivot 4, as in dotted lines in Fig. 6, for removal and replacement of a blade, and the blade holder may be swung on its pivots 11 to a position-substantially parallel to and one side of the handle to reduce the width of the razor for storage and the like'.

Having now described my invention what I claim is:
